Help/Support PUBG Mobile Crash and Bricks phone briefly

[OnlineCat 1.1k iPhone 6s 9.1]

I do not know if this problem is because of jailbroken or the sort. The game starts up and it shows the tencent logo for quite a long time ~15-25 seconds then later it just turns off my phone and i am unable to do anything for 3-5 seconds and all inputs will be put off and thhen executed all at once when it finally responses, sometimes the screen will flicker alot and i have to reboot it. If any other info is needed i will be able to give it, if it is within my power.

A game wouldn't do that, unless you've installed a previous version or something.
